Ill start off by saying Im very new to working with embedded systems and do not have much experience at all, so if I ask kind of a dumb question, at least you'll know why :smileywink:


So I am working with the DEMOACKIT from Freescale, with the MCF51AC256. 


If I was to hum into a microphone, how could I go about getting the frequency of that hum? I'm pretty sure I'll need to make use of a FIR filter but have never even heard of one before I wanted to do this.


Any help would be greatly appreciated. Again, please excuse my noviceness, I'm learning! :smileyhappy:
